When an employee works from home, your company's security depends on the robustness of their home router, the security of their personal laptop and the cybersecurity habits you've managed to instil. Without a structured framework, every remote worker is a potential entry point for a cyberattack. This guide details the technical and organisational controls you need to implement.
The Five Most Common Attack Vectors in Remote Environments
Attacks on companies with remote teams follow predictable patterns. Phishing is the number one vector: forged emails impersonating colleagues, clients or suppliers exploit the lower vigilance of the home environment. The second vector is weak or reused credentials: without a password policy and without multi-factor authentication, a single breach compromises multiple systems. The third risk is unmanaged personal devices accessing corporate data without security controls. The fourth, home or public Wi-Fi networks without encryption that expose corporate traffic. The fifth, shadow IT: employees installing unauthorised tools for convenience, unaware of the risks they introduce.
85% of security incidents in companies with remote work originate from compromised credentials or unmanaged devices.
The Essential Technical Controls
Corporate VPN
All connections to internal systems must go through a VPN with AES-256 encryption. Solutions like WireGuard, OpenVPN or Cisco AnyConnect are reliable and scalable for SMEs. Configure least-privilege access: each user accesses only what they need.
Multi-Factor Authentication (MFA)
Enable MFA on all access points: email, CRM, ERP, cloud storage. Use apps like Microsoft Authenticator or Google Authenticator, not SMS (more vulnerable). MFA blocks 99.9% of compromised credential attacks.
Endpoint Management (MDM/EDR)
Tools like Microsoft Intune, Jamf or SentinelOne let you manage and secure all devices accessing corporate data, apply disk encryption policies and detect anomalous behaviour in real time.
Zero Trust Solutions
The Zero Trust model assumes no user or device is trusted by default, even within the corporate network. Tools like Cloudflare Access or Zscaler implement this model without traditional VPN.
Security Policy for Remote Workers: What It Must Include
Technical controls are useless without a clear security policy that employees know and comply with. The policy must define which devices are authorised to access corporate systems, how passwords are managed (password manager mandatory), what to do when a suspicious security incident is detected, restrictions on public Wi-Fi networks and which communication and collaboration tools are authorised. This policy must be communicated during onboarding and reviewed at least annually. Complementing it with quarterly awareness training reduces human risk, which remains the most critical factor in any cybersecurity strategy.
